MARKING TOOL.

This invention relates to a marking tool designed primarily for use byshoemakers for the purpose of laying out on the soles of shoes, thepositions of? the nails to be driven into the soles thereby to insureregular spacing and, consequently, a better appearing finished article.

It is another object of the invention toprovide a simple and eflicientstructure of this character which can be handled readily and on whichmaybe mounted marking wheels of diiierent shapes or sizes to suit the work.

A still further object is to provide a tool in which the marking devicesare adjustably mounted.

lVit-h the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed with out departing from the spirit of theinvention.

In the accompanying drawings the pre ferred form of the invent-ion hasbeen shown.

In said drawings, Figure 1 is a side elevation of the tool. Figure 2 isa top plan View thereof. Figure 3 is section on line 3-3 Figure 2.Figure & is aside elevation of a modified form of structure.

Figure 5 is a bottom plan view thereof. Figure 6 is a section on line 66Figure 4:. Figure 7 is a section online 7-7 Figure 5. Reterring to thefigures by characters of reference 1 designates a handle from whichextends a shank 2 provided, at its outer end. with. a flat elongatedhead 3. 'Formed in this head adjacent the respective ends are threadedopenings 4: in each of which is arranged a screw 5 having a. head 6atone end.

These screws are insertable into the heads. from opposite sidesrespectively and each screw has a marking wheel 7 journaled upon thatend thereof remote from the head 6. These marking wheels, which are inthe form of star wheels are formed with mar ginal points 8 placed upondesired distances. As shown in Figure 1 one of the wheels 7 can beprovided with a. greater number of points 8 than the other wheel. Inboth structures the points are equally spaced.

The projecting end portions of the head I constitute guides and inpractice the screws 5 are adjusted so as to bring the wheels 7tl'iedesired distances from the sides of the head. In other words thedistances between the points of the wheel and the planes occupied by thesides of the head are equal to the distances at which the rows 01? nailsare to be spaced inwardly from the margin of the shoe sole. 6 After theparts have been. adjusted the tool is placed with one of the ends of thehead 3 against the side of the shoe sole and with the selected wheel 7in contact with the bottom of the sole. The tool is then pushed orpulled along the sole, the head being kept in contact with the edgethereof. Thus the point 8. of the wheel will bite into the sole, andleave depressions regularly spaced from each other and equi-distaut fromthe edge of the sole. These depressions are designed to receive thenails used in attaching the sole.

Instead of providing the structure illustrated in Figures 1, 2 and 3,the tool can be constructed as illustrated in Figures 4 to 7 inclusive.This modified structure includes a handle 9 having a shank 10 extendingtherefrom to a substantially circular head 11. Extending radially fromthis head is a 6 guide in the form of a finger 12 the active face ofwhich is preferably rounded as shown at 13 in Figure 5. A screw letextends through the center of and engages the head 11 and mounted forrotation on this screw is a disk 15 having spaced apertures 16. Any oneof these apertures is designed to receive a holding screw 17 extendingthrough the head 11 whereby the disk is held against rotation. Studs 18extend from the disk 15 toward the head 11 and journaled on these studsare marking wheels 19 similar to the wheels 7 heretofore described. Bothmarking wheels are provided with points, the points of one wheel beingspaced apart "greater distances than the points of the other wheel aswill be seen by referring particularly to Figure 4.

A channeling knife 20 is fastened to and extends beyond the periphery ofthe disk 15, this blade being so positioned relative to the wheels 19that it can be used for trimming the edge of a sole without interferencefrom the wheel and the wheels can be used for marking or laying out thepositions of the nails without interference from the blade.

In using the tool disclosed in Figures 4 to 7 inclusive the wheels 19can be adjusted relative to the guide 12 simply by disengaging screw 17from the disk 15 and then turning the screw 1% so as to shift disk 15toward or from the head 11. can then be inserted into one of theapertures 16 so as to hold the wheels 19 at proper positions relative tothe handle 9. For example if the channeling blade 20 is to be used forchanneling the sole when the sole is to be sewed, the blade is broughtto the position shown in Figure 4t and is adjusted so as to be supportedat a desired distance from the guide 12. The guide is then placedagainst the edge of the sole and the tool moved around the sole with theblade 20 cutting into the sole at the desired distance from the edge. Ifit is desired, however, to utilize one of the wheels 19 for laying outthe nail holes, the disk 15 is adjusted angularly until the selectedwheel is brought to The screw '17 position at one side of the guide 12whereupon the disk is held in place by the screw 17. Thus the screw canbe used in the same manner as the one heretofore described.

W hat is claimed is A tool of the class described including a head, aguide portion extending therefrom for sliding engagement with one edgeof the work, a centrally supported disk adjustably connected to andlocated at one side of the head a work eugaging derice carried by thedisk adjacent the periphery thereof and means extending from the headfor engaging the disk to hold it against rotation rela, tive to the headand maintain, the work engaging means in operative position.

In testimony that we claim the foregoing as our own, we have heretoaffixed our signatures.
